Jean-Baptiste LamarckJean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; French:), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield.
HagfishClass of eel-shaped, slime-producing animalHagfish, of the classMyxini (also known as Hyperotreti) and orderMyxiniformes, are eel-shaped jawless fish (occasionally called slime eels). Hagfish are the only known living animals that have a skull but no vertebral column; however, they do have rudimentary vertebrae.
Systema NaturaeSystema Naturae (originally in Latin written Systema Naturæ with the ligatureæ) is one of the major works of Swedish botanist, zoologist, and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and Johann, Linnaeus was the first to use it consistently throughout his book. The first edition was published in 1735.
BarnacleBarnacles are arthropods of the subclassCirripedia in the subphylum Crustacea. They are related to crabs and lobsters, with similar nauplius larvae. Barnacles are exclusively marine invertebrates; many species live in shallow and tidal waters. Some 2,100 species have been described. Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are specialized parasites of other crustaceans, with reduced bodies.
EchinodermAn echinoderm () is any animal of the phylum Echinodermata (), which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies". While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed radial symmetry (pentamerous symmetry), and are found on the sea bed at every ocean depth from the intertidal zone to the abyssal zone.
AnimalBiological kingdomAnimals are multicellular, eukaryoticorganisms belonging to the biologicalkingdomAnimalia (). Animals consume organic material, breathe oxygen, have muscle cells, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. With few exceptions, animals are able to move. Animals form a clade, meaning that they arose from a single common ancestor.
Carl LinnaeusSwedish biologist and physician (1707–1778)Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné, was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as Carolus Linnæus and, after his 1761 ennoblement, as Carolus a Linné.
EarthwormTerrestrial invertebrate, order OpisthoporaAn earthworm is a soil-dwelling terrestrialinvertebrate that belongs to the phylumAnnelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female.
Soft-bodied organismSoft-bodied organisms are organisms that lack rigid physical skeletons or frame, roughly corresponds to the group Vermes as proposed by Carl von Linné. The term typically refers to non-panarthropodinvertebrates from the kingdomAnimalia, although many non-vascular plants (mosses and algae), fungi (such as jelly fungus), lichens and slime molds can also be seen as soft-bodied organisms by definition.
ArthropodPhylum of invertebrates with jointed exoskeletonsArthropods ( ) are invertebrates in the phylumArthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated (metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one.
InvertebrateInvertebrates are animals that neither develop nor retain a vertebral column (commonly known as a spine or backbone), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordatesubphylumVertebrata, i.e. vertebrates. Nonetheless, almost all invertebrates belong to the monophyletic clade Protostomia, including arthropods, molluscs, annelids, and flatworms.
TaxonIn biology, a taxon is a group of one or more populations of an organism, or organisms, as seen by taxonomists to form a biological unit; (taxon: back-formation from taxonomy; pl.: taxa). Although neither is required, a taxon, once its description has become established, is usually known by a particular name and is given a particular ranking.
NematodePhylum of wormsThe nematodes ( ), roundworms or eelworms constitute the phylumNematoda (Ancient Greek: Νηματώδη; Latin: Nematoda). Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic. Parasitic worms (helminths) are the cause of soil-transmitted helminthiases. They are classified along with arthropods, tardigrades and other moultinganimals in the cladeEcdysozoa.*As an Amazon Associate I earn from qualifying purchases.
